QoS Setup
QoS (quality of service) provides for the classification of Ethernet traffic into
high and low priority queues. High priority packets are forwarded to their
destination address before a low priority packet.
Packets can be classified as high or low by MAC address, 802.1p priority tag,
and/or port ID.
WARNING: I/O devices do not support the QoS protocol.
